Backlash, there are uses for all 3 views, just need to see what works for you.....I like Perspective mode as i troll down the bank, i can see laydowns that are not visible at the surface and can fish them (bass fishing) as needed. Also if you stop and spend time on a particular structure that is found, you can flip it to forward and really "focus" on that structure......Perspective gives a wider view of whats out in front vs Forward which is a thinner "slice".
